Control, independent and dependent variables, constant variables, random assignment, and manipulation are the elements of an experimental design. These are the elements that aid in determining a valid experiment.
What are components of a valid experiment?
Control, independent and dependent variables, constant variables, random assignment, and manipulation are the elements of an experimental design. These are the elements that aid in determining whether the experiment is valid. The control, independent and dependent variables, and constants are the four fundamental elements that have an impact on an experiment's validity. To deem an experiment valid, certain fundamental conditions must be met.
Hence, in the above experiment the scientist has constant variables, dependent variable, manipulation and also control so we can easily sum that his experiment is valid.
